Description

Technical Field

[0002] The structure of the strong permanent magnetic suction cup is the same as that of the ordinary permanent magnetic suction cup. It is assembled from a panel, a magnetic steel, a base, a clamping strip and a wrench. Its characteristic is that the suction force can reach 12-15kg per square centimeter, which is between the ordinary permanent magnetic suction cup and the super strong permanent magnetic suction cup. Its appearance can be customized through the form of use.

[0003] The patent specification with announcement number CN217800336U discloses a freely spliced ​​strong permanent magnetic suction cup, which is provided with a bottom plate, a slide groove, a slider, a protrusion and a groove, wherein the top of the bottom plate is provided with a slide groove arranged in parallel, wherein the bottom of the strong permanent magnetic suction cup body is provided with a slider matching the slide groove, the left side of the strong permanent magnetic suction plate is welded with a protrusion arranged in parallel, and the right side of the strong permanent magnetic suction plate is provided with a groove matching the protrusion. When in use, the protrusion on the strong permanent magnetic suction cup body is inserted into the groove, and then the strong permanent magnetic suction cup body is fixed by fixing bolts. When it is necessary to increase the adsorption area, another strong permanent magnetic suction cup is installed on the bottom plate, and then the protrusion at one end of the strong permanent magnetic suction plate is inserted into the groove, so that the two strong permanent magnetic suction cups are spliced, thereby increasing the overall adsorption range. It has a wide range of application and is conducive to practical use.

[0004] However, in the implementation of relevant technologies, it was found that the above-designed freely spliced ​​strong permanent magnetic suction cup has the following problems: in the prior art, two sets of permanent magnetic suction cups can be spliced ​​through components such as a bottom plate and a groove to increase the adsorption range, but in actual use, the permanent magnetic suction cup is not only used for adsorption and fixation, but also for adsorbing the workpiece for transportation. During the transportation of the workpiece, it is necessary to grasp it with the permanent magnetic suction cup as the center point to maintain the balance of the lifting. If the balance cannot be maintained, it is easy to tilt, resulting in the inability to transport the workpiece. In view of this, a freely spliced ​​strong permanent magnetic suction cup is provided to overcome the above-mentioned defects. Utility Model Content
